WIRE-STRAIGHTENER;

SPECIFICATION forming part of Letters'Patent No. 710,151, datedSeptember 30, 1902.

Application filed May 23, 1902.

Serial No. 108,613. (No model.)

To all whom, it may concern:

Beit known that I, JOHN G. IVERSON, of Minneapolis, Hennepin county,Minnesota, have invented certain 'new and useful Iniprovements inWireStraighteners, ot' which the following is a specification.

This invention relates to improvements in wire-straighteners; and theobjects I have in view are to provide a simple and inexpensive 1o deviceby means of which wire may be quickly and effectively straightened.

The invention consists generally in a wirestraightener comprisingarotating'shell, stationary bearings for said shell, tubes arrangedWithin said shell and forming guides for the Wire, and means foradjusting the position of said tubes.

The invention consists, further, in the constructions and combinationshereinafter dezo scribed, and particularlypointed out Yin the claims.

In the accompanying drawings, forming part of this specification, Figure1 is a longitudinal vertical section of a wire-straightener embodyingmyinvention. Fig. 2 is asimilar View with the shell and tubes rotatedto'a position at right angles to that which they oc' cupy in Fig. 1.Fig. 3 is a transverse section on line o: a: of Fig. 2. Fig. 4 is adetail show- 3o ing a modification.

In the drawings, 2 represents the base of the machine, which may be ofany suitable size and construction. As here shown, it is in the form ofa casting having suitable uprights or standards provided With suitableopenings in which are secured the bearing-V pieces 3 and 5, which areadjustably held in position in the standards by means of suitableset-screws 7. Each of the bearings 3 'and 4o 5 is preferably ofcylindrical form and fits into a corresponding opening in the standardof the base. These bearing-pieces are longitudinally pierced by theopenings 9 and 11, and the bearing-piece 3 is preferably provided with aconical opening 13, communicating centrally with the opening 9. Eachbearingpiece has at its innery end asocket adapted to receive thecylindrical end of'the shell 15. The shell 15 is mounted in the socketsin the 5o bearing-pieces 3 and 5 and is adapted to be rotated by a beltapplied thereto. The shell may be of slightly-greater diameter at thecenter than at the ends of the outer portion, so as to be adapted toretain the belt in position thereon. A cylindrical opening extendstransversely through this shell, and a large opening extends from thiscylindrical opening to each end of the shell, a portion of the latteropening being preferably conical, as shown in the drawings. Anadjustable block 6o 17 is arranged in the transverse opening in theshell, and this block is adapted to be held in any desired position bymeans of a setscrew 19. This blockis provided at its opposite sides withsockets communicating centrally with each other, and tubes 2l, havingrounded ends, are supported each with one end in' the block 17 and itsopposite end in the bearing-piece 3 or 5. A ball-and-socket joint ispractically formed between the end of the 7o tube 21 and the block 17 orthe bearing-piece 3 or 5. These tubes are arranged loosely Within theirsupports, so that they are free to rotate upon their own axes, and theymay be adjusted to any desired inclined position Within the limits ofthe longitudinal opening in the shell. A continuous opening or passagefor the wire is formed by the openings 9 and 11 in the bearing-pieces 3and 5, the opening in the tubes 21, and the'opening through 8o the block17. K

The operation ot the device is as follows: The wire is fed through theopening 9 into the bearing-piece3 through the tubes 2l and through theopening 11 in the beari-ng-piece 85 5. The block 17 is adjusted so as toset the tubes at the desired inclination. The shell 15 is then rapidlyrotated by means of a belt applied thereto, and the block 17, which haspreviously been adjusted to the position deqo sired, causes the innerends of the tubes 21 tobe in an'eccentric position. As the shell isrotated the tubes are carried around Withit, each describing the,surface ot' a cone and reach being at the same time free to rotate uponits own axis. As the Wire passes through the tubes it is subjected to abending action in all directions and will 'emerge from the tubesstraight. There is no rotary friction between t-he tubes and the surfaceof the Wire, roo owing to the fact that the tubes are each free torotate on its own axis. The bearing-pieces 3 and 5 and tubes 21 arereadily removable and extra bearing-pieces and tubes withdifferent-sized openings for different sizes of Wire may be provided tobe employed With a single shell and adjustable block 17, or thebearing-pieces 3 and 5 may be provided with removable andinterchangeable bushings hav` ing,r openings of different diameters fordifferent sizes of Wire. I have illustrated this oonstruotion in detailin Fig. 4, in Which 24 represents a removable bushing.

I claim as my invention and desire to secure by Letters Patent- 1. Theoombination,with the rotatable shell, of an adjustable block arrangedtherein, and tubes each having one end supported in said adjustableblock and its opposite end Carried by a suitable support, substantiallyas described.

2. The eo1nbination,with the rotatable shell,

of an adjustable block arranged therein, andA tubes each having one endsupported in said adjustable block and its opposite end Carried by afixed support, substantially as described.

3. The combination,with the rotatable shell, of the adjustable blockarranged therein, and tubes, each having one end supported in said blockand its opposite end carried by a iixed support, each of said tubesrbeing free to rotate upon its own axis, substantially as described. l

4. The combination, with the stationary bearing-pieces, of the rotatableshell supported in said bearing-pieces, the adjustable block mounted insaid shell, and the tubes, each having one end mounted in said block andits opposite end mounted in one of said bearing-pieces, and eaehof saidtubes being free to rotate upon its own axis.

5. The combination, with the base 2 provided with suitable standards, ofthe bearingpieoes 3 'and 5 adj ustably supported in said standards, andprovided with central openings 9 and 11, the rotatable shell mounted insaid bearing-pieces and provided with the adjustable block 17, the tubes21 each having one end mounted in said adjustable block and its oppositeend mounted in one of said bearing-pieces, and eaeh of said tubes beingfree to rotate upon its own axis, substantially as described.

In testimony whereof I have hereunto set my hand this 20th day of May,1902.

JOHN G. IVERSON.
